Rosa hybrida shrub named &#39;AUSpanier&#39;

ABSTRACT

A variety of rose plant of the shrub class, named ‘AUSpanier’. The ‘AUSpanier’ rose is a plant having a large airy shrub with dainty gray-green foliage. The flowers of the plant are held on by thin, wiry stems and are a soft rose pink and semi-double in form that open to provide a camellia-like bloom. The fragrance of the rose is predominately myrrh, developing musk as the flower ages.

CROSS-REFERENCE TO RELATED APPLICATIONS

The current application claims priority to a European Community Plant Variety Application No. 2010/2158, filed Oct. 14, 2010, the disclosure of which is incorporated herein by reference.

CLASSIFICATION

The present invention relates to a new Rosa hybrida shrub.

VARIETY DENOMINATION

The new plant has the varietal denomination ‘AUSpanier.’

ORIGIN OF INVENTION

This invention relates to a new and distinct variety of shrub rose plant named ‘AUSpanier’, which was originated by crossing two unnamed, unpatented varieties of Rosa hybrida.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a variety of rose which is a large airy shrub with dainty, grey-green foliage; flowers that are held on thin, wiry stems with a soft rose pink and semi-double form that open to provide a camellia-like bloom and that have a predominately myrrh fragrance; and a growth that has excellent disease resistance.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from others presently available and commercial rose cultivars known to the inventor is the following combination of characteristics: dainty foliage, blooms of soft rose pink with a semi-double form, and a large airy shrub.

Asexual reproduction of the new variety by budding as performed outdoors at Bowling Green Lane in Albrighton, Britain shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘AUSpanier’ may be asexually propagated by budding. The budding successfully occurred on the plant/rootstock Rosa cv. ‘Dr. Huey’ in the United States, and Rosa dumetorum cv. ‘Laxa’ for the observed plants in the UK.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is the ‘AUSoscar’ (unpatented variety). The new rose may be distinguished from the ‘AUSoscar’ variety by the following combination of characteristics: the ‘AUSoscar’ shows a red ring around the stamens where the stamens attach to the calyx and there is a cream-colored area in the basal zone of the petals, whereas there are no such rings on the ‘AUSpanier,’ and the petals of ‘AUSpanier’ are a slightly deeper, more uniform pink. In addition, ‘AUSoscar’ also has more smaller, linear prickles, whereas the prickles on ‘AUSpanier’ are deep concave.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (2001) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 1 year-old rose plants of the new variety grown outdoors in Albrighton, Britain in the month of July. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
